Parenteral is how? This issue becomes relevant only if the attending physician prescribes to his patient any medications that must be taken in this way. How these drugs are used to treat certain diseases, and also what are the advantages of the presented method of administration, we will consider a little below.
Parenteral is how?
To answer the question posed, it is necessary to recall that such a pharmacological term is formed from two Greek para and enteron, which literally means “near” or “contrary” and “gut”, respectively. In other words, the parenteral method involves the introduction of drugs and other substances into the body, bypassing the gastrointestinal tract, where quite a few medical devices lose their effectiveness due to the effects of acids and enzymes present there.
Thus, inhalation procedures and injections are primarily referred to this method. However, today there are other, but rarely used parenteral methods. Of these, subarachnoid, transdermal, intraosseous, subconjunctival and intranasal can be distinguished. It should also be noted that all the presented methods of drug administration are used only in special cases.
How is parenteral drug administration given?
Parenteral is how? For this method of administering medications, intramuscular and intravenous injections, as well as injections under the skin, into the serous organs, etc. In this case, the administered medicinal substances have a faster and sharper overall effect than with the oral use of tablets. This is due to the fact that with this method, chemical compounds are absorbed instantly in large quantities and are not destroyed by digestive juices. That is why, when it is necessary to study the exact effect of a drug on the body, it is recommended to use the parenteral use of the substance.
In modern medicine, this method of drug administration is also preferable, and very often and only correct. This is especially necessary if you need a quick therapeutic effect or the injected drug is destroyed or not absorbed through the intestines at all. In addition, this method is actively used in cases where the patient has a disturbed swallowing process or if there are any obstacles to taking the drug by mouth.
The advantages of this method of administration
Answering the question of parenteral - this is how, you should summarize and list all the main advantages of this method of drug administration:
- The action of the administered drugs occurs much faster, which is extremely important in emergency cases, when immediate action on the internal organs is required.
- With this method, the bioavailability of substances is significantly increased.
- The effectiveness of drugs is completely independent of food intake.
- You can use drugs that are poorly absorbed into the blood from the digestive tract or destroyed by enzymes, acid, and gastric juice.
- You can use the medicine even if the swallowing process is impaired, as well as in cases where the patient is under anesthesia or simply unconscious.
